Description
Product Features
Steady management of voltage
Diodes makes the SMAZ18-13-F Zener diode, which is intended for use in a range of voltage regulation applications. It guarantees consistent and dependable voltage regulation by offering a nominal Zener voltage of 18 volts (Vz) with a tolerance of ± 5%. This diode is appropriate for medium power applications because its maximum power consumption is 1 watt.
Effective operation
This Zener diode has a maximum impedance (Zzt) of 15 ohms, which allows for minimal resistance and effective performance. A low reverse leakage current of 500 nA at 13.7 volts is another feature that guarantees little power loss when the device is in use. In the meantime, the forward voltage (Vf) is 1.2 volts at a forward current of 200mA (If), which contributes to reducing the voltage drop under forward bias circumstances.
Simple to incorporate
Another benefit of this product is that it's simple to incorporate. It is compatible with surface mount technology and comes packaged in a DO-214AC (SMA) enclosure. This makes integrating and assembling different electronic circuits easier. Furthermore, it functions dependably within a broad temperature range of -65 °C to 150 °C, making it appropriate for various applications and climatic circumstances.

In what situation does a Zener diode like SMAZ18-13-F function normally?
The Zener diode will function in the so-called reverse breakdown condition when it is functioning correctly. This diode, sometimes referred to as a voltage regulator diode, has a unique structure and is constructed of silicon. Up until a particular reverse voltage is reached, it functions similarly to a resistor. It now starts sending health signals in the other direction. It can maintain a steady voltage close to terminals thanks to its distinct behavior, which makes it helpful in circuits that regulate and limit voltage. In electronic circuits, zener diodes are usually used to stabilize voltage. They are categorized according to their breakdown voltage.
